CARPET-CLEANING MACHINE.

E'PECIFICATION forming part of Letters Patent No. 310,307, dated January 6, 1885.

Application filed December 12, 1583.

T0 aZZ whom it may concern.-

Be it known that we, JOHN B. PETERs and LOUIS M. PETERS, of Detroit, in the county of \Vayne and State of Michigan, have invented new and useful Improvements in Carpet-Cleaning Machines; and we hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to certain new and useful improvements in the construction and operation of carpet 7 cleaning machines. by means of which great perfection in result is obtained with a minimum of wear to the can pet being operated upon.

The invention consists in the peculiar construction of the various parts and their combination and operation, as more fully hereinafter described.

Figure 1 is a perspective view of our improved machine. 2 is a vertical central cross-section of the same.

In the accompanying drawings, which form a part of this specification, A represents a suitable frame to support the operating parts of the machine. I

B B B B represent each a rectangular box. These are secured at right angles to each other, as shown, and are open on the sides thus inwardly presented. They aresecured in this position and each to the other by means of inclined walls 0 C O O, the entire ends of the boxes and the spaces formed by the inclined walls being closed. At each end of the device, and at its axial center, are secured short axle-arms D, which are designed to run in or on friction-bearings E, supported by the frame, both ends of the device being alike in this particular.

F is a pulleysecured to one of these axle arms, and by means of a belt, Cr, connecting with any suitable source of power, gives a rotary motion to the machine. One side, H, of one of these boxes performs the function of a cover, it being hinged, as shown, and provided with a suitable bolt or fastening, I, to secure it in place when closed.

(No modem In operation the carpet is put into the machine through the cover H, which has been opened for that purpose, and then closed. Motion is then given to the machine, and the carpet is retained in the particular box in which it was placed until, in the rotation of the machine, the inwardly-projectiug open side of such box is vertically, or nearly so, presented from above and toward the axial center of the device, when the carpet falls into the box immediately coincident and below the axial center, the impact loosening the dirt in the fabric, which is driven out thereof in the further rotation of the machine in the next fall of the carpet and in its passage through the 'air.

e are aware that washiuginachines and coal-sitters have been constructed heretofore of a series of open-sided compartments having their sides directly constructed together, and do not claim such as our invention, for in such constructions the inclosed space is necessarily limited by the inwardly-project ing angular junctions, which are objectionable. By joining the sides of the compartments by intermediate pieces, I increase the capacity of, the device, and the said intermediate sides 0 and the sides of the perimetal compartments mutually brace and strengthen each other. It will be noticed that each of the compartments or wings B is made upon two different inclines-that is, each compartment has two sides, B, substantially parallel, and two sides 0, the sides 0 being inclined at an angle of about forty-five degrees, so that the carpet, wedged as it is apt to be in the upper compartment, in falling strikes against the inclined side 0, which joins one of the sides B of said compartment, and by its contact with this inclined side has a better opportunity to spread, and as it falls into the next one,-fiilling on the inclined side G of that compartment, such fall is so broken that the carpet is not wedged in the compartment, whereas in machines of this class having the sides of the pockets all upon the same incline the carpet, in falling from one pocket to the next one, is very apt tobccome wedged in the latter, and to be carried round in said pocket, and the result will be that the carpet will not be cleaned.

Vhat We claim as our invent-ion is i 5 A rotary carpet-cleaning machine, eonsisty ing of a series of perimetal compartments, as B, having substantially parallel sides B and inclined sides 0, said inclined sides Ojoining i and bracing the adjacent sides B 01' each two adjacent compartments, substantially as and I0 for the purpose specified.
